Muna 1966, General Electric Company yakagadzira masero emagetsi emvura zvichibva papfungwa yekufambisa mapurotoni, ichishandisa polymer membrane se electrolyte. Masero ePEM akatengeswa neGeneral Electric muna 1978. Pari zvino, kambani iyi inogadzira masero ePEM mashoma, kunyanya nekuda kwekugadzirwa kwayo kwehydrogen shoma, hupenyu hupfupi uye mari yakawanda yekudyara. Sero rePEM rine chimiro chebipolar, uye kubatana kwemagetsi pakati pemasero kunogadzirwa kuburikidza nemapuleti ebipolar, ayo anoita basa rakakosha mukuburitsa magasi anogadzirwa. Boka reanode, cathode, uye membrane zvinoumba membrane electrode assembly (MEA). Electrode inowanzo umbwa nesimbi dzinokosha dzakadai seplatinum kana iridium. Paanode, mvura inooxidized kuti igadzire okisijeni, maerekitironi nemapurotoni. Pa cathode, okisijeni, maerekitironi nemapurotoni anogadzirwa neanode anotenderera nepa membrane kuenda ku cathode, uko anoderedzwa kuti agadzire hydrogen gasi. Nheyo yePEM electrolyzer inoratidzwa mumufananidzo.
Masero ePEM electrolytic anowanzo shandiswa kugadzira hydrogen diki, ine hydrogen yakawanda inosvika 30Nm3/h uye simba rinoshandiswa rinosvika 174kW. Kana tichienzanisa nealkaline cell, huwandu chaihwo hwehydrogen hwePEM cell hunosvika padanho rese. Sero rePEM rinogona kushanda paA current density yakakwira kupfuura alkaline cell, kusvika ku1.6A/cm2, uye kushanda kwe electrolytic kuri 48%-65%. Nekuti polymer film haidziviriri kupisa kwakanyanya, tembiricha ye electrolytic cell inowanzo kuve pasi pe80°C. Hoeller electrolyzer yakagadzira tekinoroji yepamusoro yemasero ePEM electrolyzers diki. Masero anogona kugadzirwa zvichienderana nezvinodiwa, zvichideredza huwandu hwesimbi dzinokosha uye zvichiwedzera kumanikidzwa kwekushanda. Chinhu chikuru chePEM electrolyzer ndechekuti kugadzirwa kwehydrogen kunochinja zvinoenderana nesimba rinopihwa, izvo zvakakodzera kuchinja kwe hydrogen demand. Masero eHoeller anopindura kuchinja kwe 0-100% load rating mumasekonzi. Tekinoroji yaHoeller ine patent iri kuongororwa kuti ionekwe, uye nzvimbo yekuyedza ichavakwa panosvika kupera kwa2020.
Kuchena kwehydrogen inogadzirwa nemasero ePEM kunogona kusvika pa99.99%, iyo iri pamusoro pemasero ealkaline. Pamusoro pezvo, kupenya kwegasi kwakaderera kwazvo kwe polymer membrane kunoderedza njodzi yekugadzira misanganiswa inobvira moto, zvichiita kuti electrolyzer ishande pahuwandu hwemagetsi hwakaderera zvikuru. Kufambiswa kwemvura kunopihwa ku electrolyzer kunofanirwa kunge kuri pasi pe1S/cm. Nekuti kutakurwa kwemaprotoni kuburikidza ne polymer membrane kunokurumidza kupindura kukuchinja kwesimba, masero ePEM anogona kushanda nenzira dzakasiyana dzemagetsi. Kunyangwe PEM cell yave kutengeswa, ine zvimwe zvayakaipira, kunyanya mutengo wekudyara wakakwira uye mari yakawanda ye membrane uye ma electrodes akavakirwa pasimbi inokosha. Pamusoro pezvo, hupenyu hwebasa hwemasero ePEM hupfupi pane hwemasero ealkaline. Mune ramangwana, kugona kwePEM cell kugadzira hydrogen kunofanirwa kuvandudzwa zvakanyanya.
